Authorities so far have released few details after a woman and her young grandson found dead Wednesday afternoon inside a home in Walker County.

The discovery was made just before about 5 p.m. at the residence on Texas 30 just west of Interstate 45 near Huntsville, said Trooper Erik Burse, a spokesman for the Department of Public Safety.

The woman's husband reportedly called 911.

Burse said investigators have not released how the pair was found or how the woman and child died. Their names also have not been released. Reportedly, the woman is believed to be in her 50s or 60s and the child is about 2 years old.

The Texas Rangers, the Walker County Sheriff's Office and the Walker County District Attorney's Office were at the scene overnight investigating the case.

So far investigators have not released a possible motive in the killings and no arrests have been made.
